[MCL-12570] Versions which inherit and re-define a library cause corrupted downloads

Potential fixes

Download the file that's said in the "URL" and place it in the folder identified by "Path"
Run the vanilla version of the game for that version, then run the modded version.

Attempting to use the following json as a version (provided by Minecraft Forge) results in several files being corrupted on their download which results in their hashes being invalid.

If a library is defined as required in the root version and a version json inherits from it and re-declares the library, the file downloads improperly and fails to launch.

If an item is declared as a library in both 1.12.2 and a child, then it seems this behavior occurs. This also has occurred with 1.7.10 Forge files.
